I just bought used L-35 heads and used aluminum rear drums. Now I have not set eyes on these yet. I don't think the valve covers will come with the heads. I paid $300. for all of it. They are supposed to be casting number 10238181 or 10240209, they have 6 bolt holes to hold the intake on...

the crank spins 2 times to every 1 camshaft rotation. You could be 360 degrees(crank degrees) off or you could be perfect. Did you mark where the distributor was pointing before disassembly? did you turn the engine over with the distributor out? try it like you were going to. if it doesn't...

I use Fram but I heard half a story about them being garbage? Did I hear wrong or do they truely suck? Thanks in advance!

The internal combustion engine is basically an air pump. As the pistons go down, the rings seal the cylinder walls and suck in air. This is called negative pressure or vacuum. In our case air is forced into the cylinders as soon as the valves open because of the turbo. This is called forced...

the 2 white wires are the hot and ground for the o2 sensor heater. The black one is the good one for the signal to the computer.

I talked to Tom not too long ago. He checks the BB from time to time. He has lots of bow tie parts, and he does wheel stands he said so he must be rear wheel drive. I don't know what axle he is using. One of these days I am going to check his used parts trailer and find some goodies for me. :D

how loud are you without a cat and a muffler? I plan on doing this with the PTE too. But if it will draw too much attention to me I won't do it. I already have the KB big boy pipe with no muffler (still have the cat) and it sounds great.

Hu Ryde. I am interested in some L-35's as well. I hope to find a used set and do all the work myself. I want to port match the heads and remove the rough spots in the runners and smooth it out. If you get any replies please forward them to the BB so we can all benefit. Any advice on...

I was reading about porting heads in an old carb engine book. It said that you should use a rough texture on the intake runners in the heads, to keep the fuel from puddling up. In our aplication, we have fuel injection and fuel puddling does not apply. So my question is, When porting cylinder...

This is all great information on the conversion. Has anyone tried to have the vortec heads resurfaced to fix the gap. What I mean is machining the side of the head that contacts the manifold. Maybe leave a space at the top of the head for the valve cover gasket to seal? It would be like a...

I have read this somewhere and I did a search but I could not find it anywhere. Lets say I bought some used vortecs (1998 model blazer) and I wanted to get them installed on my sy. What is the procedure to get them to fit? I know someone mods them and sells them bolt on but I am on a budget...

I am going to redo my intercooler completely. I just ordered a new jabsco pump, and 2 U shaped hose so I can route the ic hoses in the passengers side fender. I have already removed my IC pipes. Do I want to pump into the cche, then the aux ic, then the ic itself? Does the pump make the...
